Cyberdiscs are some of the nastier enemies in XCOM. They fly, are immune to most Psionic attacks, dish out plenty of damage, can take a reasonable amount of punishment, and can blow up your cover. That and they just have an awesome design.

Their design alone is enough to make me want them in Overwatch 2 in some shape or form. Imagine a boss fight against Null Sector where you face something like this, where it’s only vulnerable while opened up, but will deliver punishing amounts of damage when it starts attacking.
Please, Blizzard, see if you can get one of these into OW2.
